Check the CC and CFLAGS lines in the makefile
If your C library does not support the times(3) function, change the
#define TIMES to
#undef TIMES in speed.c
If it does, check the HZ value for the times(3) function.
If your system does not define CLK_TCK it will be assumed to
be 100.0.
If possible use gcc v 2.7.?
Turn on the maximum optimising (normally '-O3 -fomit-frame-pointer' for gcc)
In recent times, some system compilers give better performace.
type 'make'
run './destest' to check things are ok.
run './rpw' to check the tty code for reading passwords works.
run './speed' to see how fast those optimisations make the library run :-)
run './des_opts' to determin the best compile time options.
The output from des_opts should be put in the makefile options and des_enc.c
should be rebuilt. For 64 bit computers, do not use the DES_PTR option.
For the DEC Alpha, edit des.h and change DES_LONG to 'unsigned int'
and then you can use the 'DES_PTR' option.
The file options.txt has the options listed for best speed on quite a
few systems. Look and the options (UNROLL, PTR, RISC2 etc) and then
turn on the relevent option in the Makefile
There are some special Makefile targets that make life easier.
make cc - standard cc build
make gcc - standard gcc build
make x86-elf - x86 assembler (elf), linux-elf.
make x86-out - x86 assembler (a.out), FreeBSD
make x86-solaris- x86 assembler
make x86-bsdi - x86 assembler (a.out with primative assembler).
If at all possible use the assembler (for Windows NT/95, use
asm/win32.obj to link with). The x86 assembler is very very fast.
A make install will by default install
libdes.a in /usr/local/lib/libdes.a
des in /usr/local/bin/des
des_crypt.man in /usr/local/man/man3/des_crypt.3
des.man in /usr/local/man/man1/des.1
des.h in /usr/include/des.h
des(1) should be compatible with sunOS's but I have been unable to
test it.
These routines should compile on MSDOS, most 32bit and 64bit version
of Unix (BSD and SYSV) and VMS, without modification.
The only problems should be #include files that are in the wrong places.
These routines can be compiled under MSDOS.
I have successfully encrypted files using des(1) under MSDOS and then
decrypted the files on a SparcStation.
I have been able to compile and test the routines with
Microsoft C v 5.1 and Turbo C v 2.0.
The code in this library is in no way optimised for the 16bit
operation of MSDOS.
When building for glibc, ignore all of the above and just unpack into
glibc-1.??/des and then gmake as per normal.
As a final note on performace. Certain CPUs like sparcs and Alpha often give
a %10 speed difference depending on the link order. It is rather anoying
when one program reports 'x' DES encrypts a second and another reports
'x*0.9' the speed.

To use this library with Bones (kerberos without DES):
1) Get my modified Bones - eBones. It can be found on
gondwana.ecr.mu.oz.au (128.250.1.63) /pub/athena/eBones-p9.tar.Z
and
nic.funet.fi (128.214.6.100) /pub/unix/security/Kerberos/eBones-p9.tar.Z
2) Unpack this library in src/lib/des, makeing sure it is version
3.00 or greater (libdes.tar.93-10-07.Z). This versions differences
from the version in comp.sources.misc volume 29 patchlevel2.
The primarily difference is that it should compile under kerberos :-).
It can be found at.
ftp.psy.uq.oz.au (130.102.32.1) /pub/DES/libdes.tar.93-10-07.Z
Now do a normal kerberos build and things should work.
One problem I found when I was build on my local sun.

libdes, Version 4.01 10-Jan-97
Copyright (c) 1997, Eric Young
All rights reserved.
This program is free software; you can redistribute it and/or modify
it under the terms specified in COPYRIGHT.
--
The primary ftp site for this library is
ftp://ftp.psy.uq.oz.au/pub/Crypto/DES/libdes-x.xx.tar.gz
libdes is now also shipped with SSLeay. Primary ftp site of
ftp://ftp.psy.uq.oz.au/pub/Crypto/SSL/SSLeay-x.x.x.tar.gz
The best way to build this library is to build it as part of SSLeay.
This kit builds a DES encryption library and a DES encryption program.
It supports ecb, cbc, ofb, cfb, triple ecb, triple cbc, triple ofb,
triple cfb, desx, and MIT's pcbc encryption modes and also has a fast
implementation of crypt(3).
It contains support routines to read keys from a terminal,
generate a random key, generate a key from an arbitrary length string,
read/write encrypted data from/to a file descriptor.
The implementation was written so as to conform with the manual entry
for the des_crypt(3) library routines from MIT's project Athena.
destest should be run after compilation to test the des routines.
rpw should be run after compilation to test the read password routines.
The des program is a replacement for the sun des command. I believe it
conforms to the sun version.
The Imakefile is setup for use in the kerberos distribution.
These routines are best compiled with gcc or any other good
optimising compiler.
Just turn you optimiser up to the highest settings and run destest
after the build to make sure everything works.
I believe these routines are close to the fastest and most portable DES
routines that use small lookup tables (4.5k) that are publicly available.
The fcrypt routine is faster than ufc's fcrypt (when compiling with
gcc2 -O2) on the sparc 2 (1410 vs 1270) but is not so good on other machines
(on a sun3/260 168 vs 336). It is a function of CPU on chip cache size.
[ 10-Jan-97 and a function of an incorrect speed testing program in
ufc which gave much better test figures that reality ].
It is worth noting that on sparc and Alpha CPUs, performance of the DES
library can vary by upto %10 due to the positioning of files after application
linkage.

Fixed the weak key values which were wrong :-(
Defining SIGACTION causes sigaction() to be used instead of signal().
SIGUSR1/SIGUSR2 are no longer mapped in the read tty stuff because it
can cause problems. This should hopefully not affect normal
applications.
Version 4.04
Fixed a few tests in destest. Also added x86 assember for
des_ncbc_encrypt() which is the standard cbc mode function.
This makes a very very large performace difference.
Ariel Glenn ariel@columbia.edu reports that the terminal
'turn echo off' can return (errno == EINVAL) under solaris
when redirection is used. So I now catch that as well as ENOTTY.
Version 4.03
Left a static out of enc_write.c, which caused to buffer to be
continiously malloc()ed. Does anyone use these functions? I keep
on feeling like removing them since I only had these in there
for a version of kerberised login. Anyway, this was pointed out
by Theo de Raadt <deraadt@cvs.openbsd.org>
The 'n' bit ofb code was wrong, it was not shifting the shift
register. It worked correctly for n == 64. Thanks to
Gigi Ankeny <Gigi.Ankeny@Eng.Sun.COM> for pointing this one out.
Version 4.02
I was doing 'if (memcmp(weak_keys[i],key,sizeof(key)) == 0)'
when checking for weak keys which is wrong :-(, pointed out by
Markus F.X.J. Oberhumer <markus.oberhumer@jk.uni-linz.ac.at>.
Version 4.01
Even faster inner loop in the DES assembler for x86 and a modification
for IP/FP which is faster on x86. Both of these changes are
from Svend Olaf Mikkelsen <svolaf@inet.uni-c.dk>. His
changes make the assembler run %40 faster on a pentium. This is just
a case of getting the instruction sequence 'just right'.
All credit to 'Svend' :-)
Quite a few special x86 'make' targets.
A libdes-l (lite) distribution.
Version 4.00
After a bit of a pause, I'll up the major version number since this
is mostly a performace release. I've added x86 assembler and
added more options for performance. A %28 speedup for gcc
on a pentium and the assembler is a %50 speedup.
MIPS CPU's, sparc and Alpha are the main CPU's with speedups.
Run des_opts to work out which options should be used.
DES_RISC1/DES_RISC2 use alternative inner loops which use
more registers but should give speedups on any CPU that does
dual issue (pentium). DES_UNROLL unrolls the inner loop,
which costs in code size.
Version 3.26
I've finally removed one of the shifts in D_ENCRYPT. This
meant I've changed the des_SPtrans table (spr.h), the set_key()
function and some things in des_enc.c. This has definitly
made things faster :-). I've known about this one for some
time but I've been too lazy to follow it up :-).
Noticed that in the D_ENCRYPT() macro, we can just do L^=(..)^(..)^..
instead of L^=((..)|(..)|(..).. This should save a register at
least.
Assember for x86. The file to replace is des_enc.c, which is replaced
by one of the assembler files found in asm. Look at des/asm/readme
for more info.
/* Modification to fcrypt so it can be compiled to support
HPUX 10.x's long password format, define -DLONGCRYPT to use this.
Thanks to Jens Kupferschmidt <bt1cu@hpboot.rz.uni-leipzig.de>. */
SIGWINCH case put in des_read_passwd() so the function does not
'exit' if this function is recieved.
Version 3.25 17/07/96
Modified read_pwd.c so that stdin can be read if not a tty.
Thanks to Jeff Barber <jeffb@issl.atl.hp.com> for the patches.
des_init_random_number_generator() shortened due to VMS linker
limits.
Added RSA's DESX cbc mode. It is a form of cbc encryption, with 2
8 byte quantites xored before and after encryption.
des_xcbc_encryption() - the name is funny to preserve the des_
prefix on all functions.
Version 3.24 20/04/96
The DES_PTR macro option checked and used by SSLeay configuration
Version 3.23 11/04/96
Added DES_LONG. If defined to 'unsigned int' on the DEC Alpha,
it gives a %20 speedup :-)
Fixed the problem with des.pl under perl5. The patches were
sent by Ed Kubaitis (ejk@uiuc.edu).
if fcrypt.c, changed values to handle illegal salt values the way
normal crypt() implementations do. Some programs apparently use
them :-(. The patch was sent by Bjorn Gronvall <bg@sics.se>
Version 3.22 29/11/95
Bug in des(1), an error with the uuencoding stuff when the
'data' is small, thanks to Geoff Keating <keagchon@mehta.anu.edu.au>
for the patch.
Version 3.21 22/11/95
After some emailing back and forth with
Colin Plumb <colin@nyx10.cs.du.edu>, I've tweaked a few things
and in a future version I will probably put in some of the
optimisation he suggested for use with the DES_USE_PTR option.
Extra routines from Mark Murray <mark@grondar.za> for use in
freeBSD. They mostly involve random number generation for use
with kerberos. They involve evil machine specific system calls
etc so I would normally suggest pushing this stuff into the
application and/or using RAND_seed()/RAND_bytes() if you are
using this DES library as part of SSLeay.
Redone the read_pw() function so that it is cleaner and
supports termios, thanks to Sameer Parekh <sameer@c2.org>
for the initial patches for this.
Renamed 3ecb_encrypt() to ecb3_encrypt(). This has been
done just to make things more consistent.
I have also now added triple DES versions of cfb and ofb.
Version 3.20
Damn, Damn, Damn, as pointed out by Mike_Spreitzer.PARC@xerox.com,
my des_random_seed() function was only copying 4 bytes of the
passed seed into the init structure. It is now fixed to copy 8.
My own suggestion is to used something like MD5 :-)
Version 3.19
While looking at my code one day, I though, why do I keep on
calling des_encrypt(in,out,ks,enc) when every function that
calls it has in and out the same. So I dropped the 'out'
parameter, people should not be using this function.
Version 3.18 30/08/95
Fixed a few bit with the distribution and the filenames.
3.17 had been munged via a move to DOS and back again.
NO CODE CHANGES
Version 3.17 14/07/95
Fixed ede3 cbc which I had broken in 3.16. I have also
removed some unneeded variables in 7-8 of the routines.
Version 3.16 26/06/95
Added des_encrypt2() which does not use IP/FP, used by triple
des routines. Tweaked things a bit elsewhere. %13 speedup on
sparc and %6 on a R4400 for ede3 cbc mode.
Version 3.15 06/06/95
Added des_ncbc_encrypt(), it is des_cbc mode except that it is
'normal' and copies the new iv value back over the top of the
passed parameter.
CHANGED des_ede3_cbc_encrypt() so that it too now overwrites
the iv. THIS WILL BREAK EXISTING CODE, but since this function
only new, I feel I can change it, not so with des_cbc_encrypt :-(.
I need to update the documentation.
Version 3.14 31/05/95
New release upon the world, as part of my SSL implementation.
New copyright and usage stuff. Basically free for all to use
as long as you say it came from me :-)
Version 3.13 31/05/95
A fix in speed.c, if HZ is not defined, I set it to 100.0
which is reasonable for most unixes except SunOS 4.x.
I now have a #ifdef sun but timing for SunOS 4.x looked very
good :-(. At my last job where I used SunOS 4.x, it was
defined to be 60.0 (look at the old INSTALL documentation), at
the last release had it changed to 100.0 since I now work with
Solaris2 and SVR4 boxes.
Thanks to Rory Chisholm <rchishol@math.ethz.ch> for pointing this
one out.
Version 3.12 08/05/95
As pointed out by The Crypt Keeper <tck@bend.UCSD.EDU>,
my D_ENCRYPT macro in crypt() had an un-necessary variable.
It has been removed.
Version 3.11 03/05/95
Added des_ede3_cbc_encrypt() which is cbc mode des with 3 keys
and one iv. It is a standard and I needed it for my SSL code.
It makes more sense to use this for triple DES than
3cbc_encrypt(). I have also added (or should I say tested :-)
cfb64_encrypt() which is cfb64 but it will encrypt a partial
number of bytes - 3 bytes in 3 bytes out. Again this is for
my SSL library, as a form of encryption to use with SSL
telnet.
Version 3.10 22/03/95
Fixed a bug in 3cbc_encrypt() :-(. When making repeated calls
to cbc3_encrypt, the 2 iv values that were being returned to
be used in the next call were reversed :-(.
Many thanks to Bill Wade <wade@Stoner.COM> for pointing out
this error.
Version 3.09 01/02/95
Fixed des_random_key to far more random, it was rather feeble
with regards to picking the initial seed. The problem was
pointed out by Olaf Kirch <okir@monad.swb.de>.
Version 3.08 14/12/94
Added Makefile.PL so libdes can be built into perl5.
Changed des_locl.h so RAND is always defined.
Version 3.07 05/12/94
Added GNUmake and stuff so the library can be build with
glibc.
Version 3.06 30/08/94
Added rpc_enc.c which contains _des_crypt. This is for use in
secure_rpc v 4.0
Finally fixed the cfb_enc problems.
Fixed a few parameter parsing bugs in des (-3 and -b), thanks
to Rob McMillan <R.McMillan@its.gu.edu.au>
Version 3.05 21/04/94
for unsigned long l; gcc does not produce ((l>>34) == 0)
This causes bugs in cfb_enc.
Thanks to Hadmut Danisch <danisch@ira.uka.de>
Version 3.04 20/04/94
Added a version number to des.c and libdes.a
Version 3.03 12/01/94
Fixed a bug in non zero iv in 3cbc_enc.
Version 3.02 29/10/93
I now work in a place where there are 6+ architectures and 14+
OS versions :-).
Fixed TERMIO definition so the most sys V boxes will work :-)
Release upon comp.sources.misc
Version 3.01 08/10/93
Added des_3cbc_encrypt()
Version 3.00 07/10/93
Fixed up documentation.
quad_cksum definitely compatible with MIT's now.
Version 2.30 24/08/93
Triple DES now defaults to triple cbc but can do triple ecb
with the -b flag.
Fixed some MSDOS uuen/uudecoding problems, thanks to
Added prototypes.
Version 2.22 29/06/93
Fixed a bug in des_is_weak_key() which stopped it working :-(
thanks to engineering@MorningStar.Com.
Version 2.21 03/06/93
des(1) with no arguments gives quite a bit of help.
Added -c (generate ckecksum) flag to des(1).
Added -3 (triple DES) flag to des(1).
Added cfb and ofb routines to the library.
Version 2.20 11/03/93
Added -u (uuencode) flag to des(1).
I have been playing with byte order in quad_cksum to make it
compatible with MIT's version. All I can say is avid this
function if possible since MIT's output is endian dependent.
Version 2.12 14/10/92
Added MSDOS specific macro in ecb_encrypt which gives a %70
speed up when the code is compiled with turbo C.
Version 2.11 12/10/92
Speedup in set_key (recoding of PC-1)
I now do it in 47 simple operations, down from 60.
Thanks to John Fletcher (john_fletcher@lccmail.ocf.llnl.gov)
for motivating me to look for a faster system :-)
The speedup is probably less that 1% but it is still 13
instructions less :-).
Version 2.10 06/10/92
The code now works on the 64bit ETA10 and CRAY without modifications or
#defines. I believe the code should work on any machine that
defines long, int or short to be 8 bytes long.
Thanks to Shabbir J. Safdar (shabby@mentor.cc.purdue.edu)
for helping me fix the code to run on 64bit machines (he had
access to an ETA10).
Thanks also to John Fletcher <john_fletcher@lccmail.ocf.llnl.gov>
for testing the routines on a CRAY.
read_password.c has been renamed to read_passwd.c
string_to_key.c has been renamed to string2key.c
Version 2.00 14/09/92
Made mods so that the library should work on 64bit CPU's.
Removed all my uchar and ulong defs. To many different
versions of unix define them in their header files in too many
different combinations :-)
IRIX - Sillicon Graphics mods (mostly in read_password.c).
Thanks to Andrew Daviel (advax@erich.triumf.ca)
Version 1.99 26/08/92
Fixed a bug or 2 in enc_read.c
Fixed a bug in enc_write.c
Fixed a pseudo bug in fcrypt.c (very obscure).
Version 1.98 31/07/92
Support for the ETA10. This is a strange machine that defines
longs and ints as 8 bytes and shorts as 4 bytes.
Since I do evil things with long * that assume that they are 4
bytes. Look in the Makefile for the option to compile for
this machine. quad_cksum appears to have problems but I
will don't have the time to fix it right now, and this is not
a function that uses DES and so will not effect the main uses
of the library.
Version 1.97 20/05/92 eay
Fixed the Imakefile and made some changes to des.h to fix some
problems when building this package with Kerberos v 4.
Version 1.96 18/05/92 eay
Fixed a small bug in string_to_key() where problems could
occur if des_check_key was set to true and the string
generated a weak key.
Patch2 posted to comp.sources.misc
Version 1.95 13/05/92 eay
Added an alternative version of the D_ENCRYPT macro in
ecb_encrypt and fcrypt. Depending on the compiler, one version or the
other will be faster. This was inspired by
Dana How <how@isl.stanford.edu>, and her pointers about doing the
*(ulong *)((uchar *)ptr+(value&0xfc))
vs
ptr[value&0x3f]
to stop the C compiler doing a <<2 to convert the long array index.
Version 1.94 05/05/92 eay
Fixed an incompatibility between my string_to_key and the MIT
version. When the key is longer than 8 chars, I was wrapping
with a different method. To use the old version, define
OLD_STR_TO_KEY in the makefile. Thanks to
viktor@newsu.shearson.com (Viktor Dukhovni).
Version 1.93 28/04/92 eay
Fixed the VMS mods so that echo is now turned off in
read_password. Thanks again to brennan@coco.cchs.su.oz.AU.
MSDOS support added. The routines can be compiled with
Turbo C (v2.0) and MSC (v5.1). Make sure MSDOS is defined.
Patch1 posted to comp.sources.misc
Version 1.92 13/04/92 eay
Changed D_ENCRYPT so that the rotation of R occurs outside of
the loop. This required rotating all the longs in sp.h (now
called spr.h). Thanks to Richard Outerbridge <71755.204@CompuServe.COM>
speed.c has been changed so it will work without SIGALRM. If
times(3) is not present it will try to use ftime() instead.
Version 1.91 08/04/92 eay
Added -E/-D options to des(1) so it can use string_to_key.
Added SVR4 mods suggested by witr@rwwa.COM
Added VMS mods suggested by brennan@coco.cchs.su.oz.AU. If
anyone knows how to turn of tty echo in VMS please tell me or
implement it yourself :-).
Changed FILE *IN/*OUT to *DES_IN/*DES_OUT since it appears VMS
does not like IN/OUT being used.
Libdes posted to comp.sources.misc
Version 1.9 24/03/92 eay
Now contains a fast small crypt replacement.
Added des(1) command.
Added des_rw_mode so people can use cbc encryption with
enc_read and enc_write.
Version 1.8 15/10/91 eay
Bug in cbc_cksum.
Many thanks to Keith Reynolds (keithr@sco.COM) for pointing this
one out.
Version 1.7 24/09/91 eay
Fixed set_key :-)
set_key is 4 times faster and takes less space.
There are a few minor changes that could be made.
Version 1.6 19/09/1991 eay
Finally go IP and FP finished.
Now I need to fix set_key.
This version is quite a bit faster that 1.51
Version 1.52 15/06/1991 eay
20% speedup in ecb_encrypt by changing the E bit selection
to use 2 32bit words. This also required modification of the
sp table. There is still a way to speedup the IP and IP-1
(hints from outer@sq.com) still working on this one :-(.
Version 1.51 07/06/1991 eay
Faster des_encrypt by loop unrolling
Fixed bug in quad_cksum.c (thanks to hughes@logos.ucs.indiana.edu)
Version 1.50 28/05/1991 eay
Optimised the code a bit more for the sparc. I have improved the
speed of the inner des_encrypt by speeding up the initial and
final permutations.
Version 1.40 23/10/1990 eay
Fixed des_random_key, it did not produce a random key :-(
Version 1.30 2/10/1990 eay
Have made des_quad_cksum the same as MIT's, the full package
should be compatible with MIT's
Have tested on a DECstation 3100
Still need to fix des_set_key (make it faster).
Does des_cbc_encrypts at 70.5k/sec on a 3100.
Version 1.20 18/09/1990 eay
Fixed byte order dependencies.
Fixed (I hope) all the word alignment problems.
Speedup in des_ecb_encrypt.
Version 1.10 11/09/1990 eay
Added des_enc_read and des_enc_write.
Still need to fix des_quad_cksum.
Still need to document des_enc_read and des_enc_write.
Version 1.00 27/08/1990 eay

Thanks for hints from Richard Outerbridge - he told me IP&FP
could be done in 15 xor, 10 shifts and 5 ands.
When I finally started to think of the problem in 2D
I first got ~42 operations without xors. When I remembered
how to use xors :-) I got it to its final state.

Notes.
[1] For the ultra sparc, SunC 4.0
cc -xtarget=ultra -xarch=v8plus -Xa -xO5, running 'des_opts'
gives a speed of 344,000 des/s while 'speed' gives 459,000 des/s.
I'll record the higher since it is coming from the library but it
is all rather weird.
[2] Similar to the ultra sparc ([1]), 181,000 for 'des_opts' vs 175,000.
[3] I was unable to get access to this machine when it was not heavily loaded.
As such, my timing program was never able to get more that %30 of the CPU.
This would cause the program to give much lower speed numbers because
it would be 'fighting' to stay in the cache with the other CPU burning
processes.
